EVOLVE YOUR OWN AI ROBOT! You are the (zoo)Keeper overseeing a population of evolving AI robots in a dynamic voxel landscape. These robotic animats walk, jump, eat, mate, fight, and adapt to their surroundings as they strive to survive and reproduce. In theory, the capacity for their intelligence is limitless, as their brains can evolve to any shape and complexity. Will you choose to passively observe their evolution, letting nature take its course? Or will you intervene, shaping their world and influencing their evolutionary path? Design your own animal robots, build custom terrains, manipulate the environment, interact with the animals, and watch as each generation learns, adapts, and competes in a simulated ecosystem that’s as unpredictable as nature itself. The fate of their evolution is in your hands. --------- Introducing a new god game and evolutionary simulation, where you evolve the brains of artificial animals to make them more intelligent, to better achieve survival and reproduction. The animals are real AI robots running directly on your computer. They are controlled by classic neural networks and other types of AI such as non-axiomatic reasoning system. They have a simple form of vision sense, touch sensation, and internal sensations, and they can move each individual body segment. They can eat, mate, and fight, all while learning and evolving in a sandbox voxel environment. Watch evolution passively, or enjoy various interactive features including: + Voxel World: place voxels and modify the environment with sand, stone, water, and more. + Impact Evolution using your Research Journal: modify mutation rates in your Research Journal -- higher rates means faster but more unstable evolution, lower rates means slower but more stable evolution. + Pick up animats: Pick up animats and move the animats around with left click. + Build your own Robot: Go to the Animat Creator from the main menu to create your own robot. You can save it and load it into a simulation to evolve its brain!
